  • Publication number: 20210357709
    Abstract: In an object determination apparatus, a same-object determiner is configured to make a same-object determination as to whether a first object ahead of a subject vehicle that is a vehicle carrying the object determination apparatus, detected by an electromagnetic wave sensor, and a second object ahead of the subject vehicle, detected by an image sensor, are the same object. A candidate-object identifier is configured to identify a candidate for the first object, between which and the second object the same-object determination is to be made, as a candidate object. A candidate-object selector is configured to, in response to there being a plurality of the candidate objects, preferentially select, from the plurality of candidate objects, a candidate object whose likelihood for the identified object type of the second object is higher than a predetermined likelihood threshold, as a candidate object to be subjected to the same-object determination.

  • Patent number: 11133338
    Abstract: FET IC structures that enable formation of integrated capacitors in a “flipped” SOI IC structure made using a back-side access process, such as a “single layer transfer” (SLT) process, and which eliminate or mitigate unwanted parasitic couplings to a handle wafer. In some embodiments, a conductive interconnect layer may be patterned, pre-SLT, to form an isolated first capacitor plate. In other embodiments, pre-SLT, a conductive region of the active layer of an IC may be patterned to form an isolated first capacitor plate, with one or more interconnect layers being fabricated in position to form an electrical contact to the first capacitor plate. In either case, a post-SLT top-side layer of conductive material may be patterned to form a second capacitor plate. Couplings to the resulting capacitor structures include only external connections, only internal connections, or both internal and external connections.
